What should I do when the error code E2 ("‰ƒ" or similar element overheat error) appears on the display?

The E2 error indicates the element is too hot and has turned off automatically. Remove the pans from the elements and press the display to clear the error once the element has cooled down sufficiently. If the error reappears after turning the element back on, the cooktop is still too hot — turn off all elements and allow them to cool further. (Page 21)
